Word History

Etymology

borrowed from German Anthocyanin, from Anthocyan, Anthokyan, an earlier name (from Greek antho- antho- + kyan-, in kyánōs "blue color") + -in -in entry 1 — more at cyan-

Note: Anthokyan was coined by the German pharmacist Ludwig Clamor Marquart (1804-81), in Die Farben der Blüthen (Bonn, 1835), p. 55: Anthokyan (von ἄνθος Blume, und κυάνωσις blaue Farbe) ist der färbende Stoff in der blauen, violetten und rothen und vermittelt ebenfalls die Farbe aller braunen und vieler pomeranzfarbigen Blumen ("Anthokyan [from ánthos flower, and kyánōsis blue color] is the coloring matter in blue, violet and red flowers, and imparts in any case color to all brown and many orange flowers"). A German form with the suffix -in and an English form with the suffix -ine were in use by the 1850's.
